Introduction

Circuit training, also referred to as circuit therapy and circuit class therapy, comprises repetitive practice of task-specific exercises and activities. Participants typically perform progressive functional exercises as a series of workstations or individualized exercises. Circuit training commonly addresses goals relating to improved mobility and/or use of the affected upper extremity. Circuit training can be performed individually or in a group setting (at least 2 participants per therapist). The group format is believed to be advantageous as it allows participants to observe others completing similar movements or exercises, and the social element may also aide compliance (English & Hillier, 2010).

Patient/Family Information

What is circuit training?

Circuit training is a form of training that uses repetitive exercises based on real-life activities. Exercises are performed in a ‘circuit’ of workstations or as a series of individual movements. Circuit training exercises are used to improve physical abilities such as balance, strength, mobility or coordination. Circuit training can be done in small groups or one-to-one.

Why use circuit training after a stroke?

It is common to need rehabilitation after a stroke. Circuit training can be used as well as, or instead of, traditional rehabilitation to improve physical abilities. Circuit training can be used at all stages of stroke recovery – from the acute phase (approximately 1 month after the stroke) through to the chronic phase (6 or more months post-stroke). Your rehabilitation specialist can choose activities that suit your stage of recovery and rehabilitation goals. Activities can be made more or less difficult, depending on your ability. Furthermore, circuit training can be done in groups, which can benefit motivation and social interactions.

Is circuit training effective after a stroke?

Current research shows that circuit training is at least as effective as traditional rehabilitation for improving most physical abilities. In fact, many studies show that circuit training is more effective than regular rehabilitation for some outcomes. Circuit training is also shown to be as effective as traditional rehabilitation methods for improving emotional wellbeing, quality of life and cognitive function.

Are there different kinds of circuit training?

Circuit training can be used to improve different physical skills such as mobility, balance, and function (i.e. use) of the arms and legs. Different exercises can be chosen by the rehabilitation clinician to suit the patient’s rehabilitation needs. Circuit training can be done individually or in a small group. The format of circuit training will be determined by the rehabilitation centre.

Are there risks or side effects?

If you are medically cleared to participate in physical rehabilitation after your stroke, there are no specific risks or side effects associated with circuit training. It is very important that the circuit training program be developed by a qualified professional to suit the person’s rehabilitation goals and level of ability. High quality studies have shown that circuit training is not associated with a higher risk of falls than other forms of rehabilitation.

Who provides circuit training?

Circuit training is often provided by physiotherapists, but can also be provided by occupational therapists, kinesiologists, or other qualified professionals. Group circuit training programs may have more than one therapist or therapy assistant, according to the number of participants. Circuit training can be provided in inpatient or outpatient settings such as acute care hospitals and rehabilitation centers.

How much does it cost?

The cost of circuit training depends on public health or insurance policies. In Canada, costs are covered if you are receiving care in a rehabilitation setting that offers this form of treatment. If you are receiving private rehabilitation, it is important to verify that your insurance covers circuit training.

How long does it take?

In the studies reviewed, circuit training was provided for 3 to 6 weeks (most commonly 4 weeks duration). Circuit training was provided for approximately 30-60 minutes per session, and sessions were provided 3 to 5 times per week. In real life rehabilitation settings, the frequency and duration of circuit training may vary from these timeframes. Sessions are often shorter and more frequent in the early stages of stroke recovery (i.e. 1-6 months post-stroke). Sessions can be affected by the individual’s wellness, and their ability to tolerate exercise. Circuit training may end when the person reaches their rehabilitation goals (e.g. being able to return home safely). Other factors such as organisation of care or individual medical restrictions can also affect the duration of treatment.

Is circuit training for me?

Circuit training is a feasible form of rehabilitation to help recover and improve physical ability after a stroke. Speak with your rehabilitation specialists to decide if circuit training is suitable for you.

Clinician Information

Note: When reviewing the findings, it is important to note that they are always made according to randomized clinical trial (RCT) criteria – specifically as compared to a control group. To clarify, if a treatment is “effective” it implies that it is more effective than the control treatment to which it was compared. Non-randomized studies are no longer included when there is sufficient research to indicate strong evidence (level 1a) for an outcome.

A total of 25 studies (15 high quality RCTs, five fair quality RCTs, two poor quality RCTs and three non-randomized studies) that investigate the use of circuit training in post-stroke rehabilitation were reviewed in this StrokEngine module. Circuit training programs were typically oriented towards lower limb impairment and included functional tasks relating to mobility such as balance, transfers, walking, stepping and using stairs. Frequency of circuit training intervention programs varied from 30 to 180 minutes/day, 3 to 7 days/week, for 2 to 52 weeks duration. Control groups included standard care, upper extremity circuit training, non-task-specific upper or lower extremity rehabilitation, gait training, individual task-oriented exercise, neurodevelopmental treatment, individual physiotherapy, cognition training, stretching/weight-shifting exercises, social and educational classes, stretching or no rehabilitation.

A recent Cochrane review on circuit class therapy (English, Hillier & Lynch, 2017) that comprised 17 RCTs or controlled clinical trials reported statistically significant differences in favour of circuit training compared to control interventions for walking endurance, gait speed, gait cadence, mobility, balance confidence, physical stroke outcomes, fitness and daily physical activity. The review concluded that circuit training is effective for improving walking after stroke regardless of time since stroke, and that it may be effective for improving cardiorespiratory fitness and increasing daily physical activity. All but three of the 17 RCTs from the Cochrane review met criteria for inclusion in this StrokEngine module. A subsequent meta-analysis by Bonini-Rocha et al. (2018) conducted a quantitative analysis of eight RCTs (seven of the studies were considered suitable for inclusion in this StrokEngine module; six of the studies were included in the 2017 Cochrane review by English, Hillier & Lynch). This meta-analysis reported that circuit-based exercises focusing on balance and mobility showed statistically significant differences in gait speed (but not balance and functional mobility) compared to control groups.

This StrokEngine module includes studies in which circuit training was provided to individuals or groups. Some circuit training programs included upper extremity activities, whereas other studies used upper extremity circuit training as a control group. Accordingly, effort has been made to draw comparisons between (i) circuit training and control interventions, and (ii) lower extremity circuit training and upper extremity circuit training.

Overall, circuit training was found to be more effective than control treatments for improving upper extremity motor activity and walking speed in the acute phase of stroke recovery; gait impairment, gait parameters and walking independence in the subacute phase of stroke recovery; and balance/falls, cognitive function, gait parameters, lower extremity muscle strength and walking endurance in the chronic phase of stroke recovery. While circuit training was not more effective than control treatments for other outcomes, it was in most instances as effective as them. This indicates that circuit training can be considered as a potentially cost-effective option that results in comparable outcomes to conventional interventions.

Comparison of upper extremity (UE) circuit training and lower extremity (LE) circuit training in the subacute phase of stroke recovery showed that UE circuit training was more effective than LE circuit training for improving dexterity, whereas LE/mobility circuit training was more effective than UE circuit training for improving balance, mobility and walking endurance. Similarly, in the chronic phase of stroke recovery LE circuit training was more effective than UE circuit training for improving balance, transfers, walking endurance and walking speed.

Three high quality RCTs (Verma et al., 2011; van de Port et al., 2012; Kim et al., 2016) investigated the effect of circuit training on Activities of Daily Living (ADLs) in patients in the subacute phase of stroke recovery.

The first high quality RCT (Verma et al., 2011) randomized patients to receive group mobility circuit training + motor imagery or dose-matched conventional lower extremity rehabilitation using the Bobath approach for 2 weeks. ADLs were measured by the Barthel Index (BI –Toilet transfer, Transfer chair and bed, Ambulation, Stair climbing, Total scores) at follow-up only (6 weeks). Significant between-group differences were found (BI –Toilet transfer, Ambulation, Stair climbing, Total scores), in favour of circuit training vs. conventional lower extremity rehabilitation.

The second high quality RCT (van de Port et al., 2012) randomized patients to receive group mobility circuit training or conventional physiotherapy. ADLs were measured by the Nottingham Extended Activities of Daily Living (NEADL – Mobility, Kitchen, Domestic, Leisure scores) at post-treatment (12 weeks) and follow-up (24 weeks). A significant between-group difference was found on one score (NEADL – Leisure) at post-treatment, in favour of conventional physiotherapy vs. circuit training. No significant between-group differences were found at follow-up.

The third high quality RCT (Kim et al., 2016) randomized patients to receive group mobility and fitness circuit training or conventional physiotherapy. ADLs were measured by the modified Barthel Index (Korean version) at post-treatment (4 weeks). No significant between-group difference was found.

Conclusion: There is conflicting evidence (level 4) regarding the effect of circuit training on Activities of Daily Living (ADLs) in patients in the subacute phase of stroke recovery). While one high quality RCT found that circuit training + motor imagery was more effective than a comparison intervention (conventional lower extremity rehabilitation) on several measures of ADLs; another high quality RCT that used the same outcome measure found no significant difference between circuit training vs. conventional physiotherapy (in fact, this high quality RCT found that conventional physiotherapy was more effective than the circuit training). Furthermore, another high quality RCT found that circuit training was more effective than conventional physiotherapy on only one measure of ADLs.

Conclusion: There is strong evidence (level 1a) from three high quality RCTs and one non-randomized study that circuit training is not more effective than comparison interventions (conventional physiotherapy, intensive physiotherapy, progressive task training) for improving upper extremity motor function in patients in the subacute phase of stroke recovery.

Satisfaction
Not effective
2B

One non-randomized study (English et al., 2007) investigated the effect of circuit training on satisfaction in patients in the subacute phase of stroke recovery. This non-randomized study assigned patients to receive group mobility and upper extremity circuit training or individual physiotherapy during inpatient rehabilitation. Patient satisfaction was measured by an adapted version of the Pound Scale at week 4 of rehabilitation, on discharge from rehabilitation and at follow-up (6 months post-stroke). A significant between-group difference in patients’ satisfaction with the amount of therapy received was found at 6-month follow-up only, in favour of circuit training vs. physiotherapy.

Conclusion: There is limited evidence (level 2b) from one non-randomized study that circuit training is not more effective than a comparison intervention (conventional physiotherapy) for improving patient satisfaction in patients in the subacute phase of stroke recovery.
Note:
However, this non-randomized study found a significant between-group difference in patient satisfaction with amount of physiotherapy received at 6 months post-stroke, in favour of circuit training.

Shoulder pain
Not effective
2b

One non-randomized study (English, Hillier & Stiller, 2008) investigated the effect of circuit training on shoulder pain in patients in the subacute phase of stroke recovery. This non-randomized study assigned patients to receive group mobility and upper extremity circuit training or individual physiotherapy during inpatient rehabilitation. Shoulder pain was measured according to incidence (yes/no response) and severity (visual analogue scale) at week 4 of rehabilitation and on discharge from rehabilitation. No significant between-group differences in incidence or severity of shoulder pain were found at either time point.

A significant between-group difference in one measure (SIS – Memory and thinking) was found at post-treatment, in favour of conventional physiotherapy vs. circuit training. Differences did not remain significant at follow-up.

The second high quality RCT (English et al., 2015) randomized patients with subacute stroke to receive group circuit training, time-matched physiotherapy (5 days/week), or intensive physiotherapy (7 days/week). Stroke outcomes were measured using the SIS (Physical subscale) at post-treatment (4 weeks). No significant between-group differences were found.

The fair quality RCT (Kim, Jung & Lee, 2017) randomized patients to receive group balance and gait circuit training or individual task-oriented lower extremity rehabilitation; both groups also received neuro-developmental treatment. Walking endurance was measured by the 6MWT at post-treatment (4 weeks). A significant between-group difference was found in favour of circuit training vs. task-oriented lower extremity rehabilitation.

The non-randomized study (English et al., 2007) assigned patients to receive group mobility and upper extremity circuit training or individual physiotherapy during inpatient rehabilitation. Functional walking capacity was measured by the Two Minute Walk Test at week 4 of rehabilitation, on discharge from rehabilitation, and at follow-up (6 months post-stroke).

Conclusion: There is moderate evidence (level 1b) from one high quality RCT that mobility circuit training is more effective than upper extremity circuit training for improving walking endurance following stroke.

One high quality RCT (Salbach et al., 2004) investigated the effect of circuit training on walking speed following stroke. This high quality RCT randomized patients with subacute/chronic stroke to receive group mobility circuit training or group upper extremity circuit training. Walking speed was measured by a 5-meter walk test (comfortable walking speed, maximum walking speed) at post-treatment (4 weeks). Significant between-group differences in comfortable and maximum walking speeds were found, in favour of mobility circuit training vs. upper extremity circuit training.

Conclusion: There is moderate evidence (level 1b) from one high quality RCT that mobility circuit training is more effective than upper extremity circuit training for improving walking speed following stroke.
